Electronic universal testing machine is a new generation of double space microcomputer controlled electronic universal testing machine specially designed for higher education institutions and scientific research institutes in China. The design of the main machine and accessories of the testing machine mainly draws lessons from the advanced information technology of Shimadzu, Japan. It has beautiful appearance, simple and convenient operation, stable performance, safety and reliability. It can meet our national and international economic related working standards. The computer network system of the electronic universal testing machine mainly controls the rotation of the servo motor through the controller and the internal control of the speed regulation system. After the deceleration of the deceleration system, the precision lead screw pair drives the beam of China Mobile to rise and fall, so as to complete the tensile, compression, bending, shear and other mechanical property tests of the sample. Next, I will introduce the relevant theories on the operating procedures of the electronic universal testing machine and how to effectively solve these external environmental disturbances. Let's have a look.

Operating procedures of electronic universal testing machine and how to solve external interference

1、 Operating procedures for electronic universal testing machine

1. Turn on the electronic testing machine in sequence (preheat for 15 minutes), and then turn on the power switch of the student computer.

2. Place the test bench to be tested, adjust the lifting button of the testing machine to ensure the accuracy of the test, and clamp the test piece.

3. The computer opens the software to enter the main interface; First check whether it is the corresponding standard test.

4. When returning to the main interface, clear the "real-time force value", "displacement", "deformation" and "peak force value" to zero.

5. Click the right triangle button to start the test.

6. When the "real-time force value" begins to decline and the "real-time force value" is significantly lower than the "peak force value", you can stop the test by clicking the box button, or use the test machine to return automatically (this service function needs to be set in the test design scheme), record the "peak force value" and compare the standard development to make analysis and test research results as judgment.

7. After the electronic universal testing machine completes the test, clean the dust and test objects on the universal testing machine, first turn off the power supply of the testing machine, then turn off the software, and then turn off the computer.

2、 How to solve the external interference of enterprises with electronic universal testing machine

1. Electromagnetic interference.

The performance of electromagnetic interference is that the force value of electronic universal material testing machine fluctuates greatly. In view of this interference, check whether long and thin wires are applied to the grounding system and whether the shielding wire of the sensor plays a role.

2. Interference caused by input voltage.

This phenomenon can be caused by lightning stroke or the current introduced by the power line. It will burn the fuse, damage the circuit board of the universal material testing machine and damage the AC servo controller.

3. Alternating current interference

Alternating current will also interfere with the electronic universal testing machine. Although there will be no problems in a short time, the longer the time, the greater the circuit damage. Therefore, for this kind of interference, the use of regulated power supply with filtering effect on interference is the best way.

4. Inductive interference

Induced interference is caused by the electromagnetic field generated by the surrounding equipment. Inductive interference will damage the electronic tension compression testing machine, so it is necessary to install electromagnetic signal isolator or stay away from the interference source.

The above problems are the operating procedures of electronic universal testing machine shared by Xiaobian and the relevant theoretical knowledge of how enterprises solve the interference of external environment. I hope it will be helpful to you. The mechanical equipment is essentially the same as us. Only by mastering the correct methods can the whole experimental research process be smoother and the experimental analysis data be more accurate.
